For some reason at 5:38 pm we (AS18883, FiberNet) lost IPv4 and IPv6 peering with both of MICE RR's and Hurricane Electric and it's been unstable since then. All our other peers with MICE are fine. I didn't change any configuration, even though the "bad AS number" note in some of the error messages would suggest that. Any hints would be welcomed. I've shutdown those six sessions for now.
